Its okay, not every one has, the creator of soylent brags about not having studied nutrition.
I have. Most meal replacement companies hire teams of certified nutritionists to formulate their products.
I see this conversation is going nowhere. That obviously, so obviously, isn’t what I’m saying. ~sighs~ Again lets refrain from schoolyard insults, this is the second request.
Soylent lists their ingredients, as do all meal replacement manufactures. No need for anyone to speculate at all, be rude, or demand any proof of anything. Anyone can look at the ingredients, and look up any they aren’t familiar with themselves, and make their own determinations based on the facts.
The number of studies I found in less then 1min was only listed because you doubted ANY had been done, which is in direct antithesis to the entire nature of the meal replacement industry. I wasn’t citing any of them, only pointing out that whether or not there have been studies doesn’t have to be blind speculation or a baseless assumption. same with whether or not a mineral is the most or least bio-available form or where it is typically sourced from doesn’t have to be blind speculation. none of this conversation needs any speculation whatsoever, it is all easily accessible information. If you don’t know, why argue so?
Like i said the soy protein isolate is the highest quality ingredient they use, and i pointed out that it is the cheapest and lowest quality way to get a complete amino acid profile. i pointed this out, because i already knew all of this. yes, for a single source of proteins it has a very complete amino acid profile, which is why it gets the 1.0 rating, but it contains much less BCAAs or free peptides and the ratio of those amino acids aren’t in as good of a balance ratio for humans, but it is super cheap and complete. This is why it is the source of protein for MOST meal replacements, and the source of protein for all cheap protein powders, but all the high end ones use protein source from whey/casein/eggs and typically use a blended source, because they aren’t just ticking all the boxes, they are making sure the balance and source is the optimal one. Again, it is the cheapest lowest quality way to get a complete amino acid profile, that is not in contradiction to being one of the best single source food sources with a complete essential amino acid profile (the 1.0 rating), this is why it is the source used by most meal replacements. Soy protein in fine, hence my assertion that it the best ingredient in the list.
Please see the limitations section of the PDCAAS link.
exactly this! 
teams of nutritionists and clinical trials for most products formulation. As you pointed out the creator of soylent brags about not being a nutritionist and making a checklist of the bodies needs and finding the cheapest way to check off each box. I guess if you don’t understand nutrition that well or bio-availability and are a “bio-hacker”, whatever that is, this approach might seem to make sense, unfortunately it doesn’t lead to the highest quality product as we’ve both pointed out. 
That is silly. Do you really think the FDA would allow hospitals to use a product with 100% lethality rate? Or even allow such a product to be sold? The entire point of these studies is to determine the products safety and measure markers such as bone density, muscle loss, metabolic markers, mineral excretion, etc. The type of things you want to be damn certain of if you are replacing actual meals, as not everyone is using them as a quick breakfast alternative.
